I also went the route of skipping steps 4-16. If you do this, be careful with the front panel since you have just enough room to turn it while it's connected to give you access to the vibrator assembly. The angled tweezers (Part # IF145-020-5) were a lifesaver for replacing the two tiny screws to the vibrator assembly. Also, you might have an issue vibrate not working after you replace the front panel. I fixed this by pushing on the vibrator assembly a splunger while giving each screw another slight turn. It's barely noticeable, but doing that should allow the vibrator to work without hitting the front panel assembly.
